Introduction

The PR500, HD500-2, SP500 and PM500 Proximity Readers are

designed to read the codes contained in Cotag coded cards and tags

and to pass these codes, if valid, to a host system. These Readers are

primarily for use by OEMs to provide proximity reading for their own

proprietary access control systems.

Each Reader requires a power supply, but can usually share the

same supply as the door lock.

Reader types

The PR500 Proximity Reader is a general purpose proximity reader

which is small and slim and can be mounted on a wall or door frame.

The HD500-2 Heavy Duty Proximity Reader has a stainless steel

frame, held in place by four tamper-resistant screws, which covers

the mounting screws. This makes it suitable for applications where

vandalism could be a problem.

The SP500 Switch Plate Proximity Reader fits a standard single

surface-mount or flush fitting back box, either metal or plastic, such

as is used for light switches and mains plug sockets2-hole mounting

for screwing it to a standard single-way back box.

The PM500 Panel Mount Proximity Reader can be mounted within a

sheet metal or plastic panel using four screws.

Data output

The Readers provide Wiegand or Magnetic Stripe format data output,

or ASCII data output at TTL voltage levels (0V and +5V). (The Readers

are available in AB format if you require BCLINK data output, but

this option is not described in this handbook.)

For some OEM systems, the data lines from two Readers can be

connected in parallel, the host polling each Reader in turn using the

Data Hold input. When this input is held low, the Reader buffers the

data from one transaction. The host must release the Data Hold line

and read the message before the next card is read, or else the

message is discarded by the Reader.

Proximity Readers Handbook

1-2

Interrogation of cards and tags

The Reader uses “standard interrogation” which reads the card code

just once and outputs the data in a little under half a second for

standard cards and tags, or in one tenth of a second for fast cards

and tags. If there is too much electrical noise to read a card or tag,

the amber LED indicator on the unit flashes.

The interrogation routine checks both the Distributor Code and the

Secondary Code* of a card or tag and sends data to the host system

only if both are valid.

*Note that the Secondary Code check can be disabled with some

interfaces - see chapter 3 for details.

Setting up the Reader

You configure the Reader by presenting it with two coded cards. The

first card (the configuration card) defines the type of data interface,

and various other features*. The second card (any of the ordinary

Distributor Coded cards which will be used with the system) teaches

the Reader its Distributor and Secondary Codes. Note that you

cannot teach the Reader its Distributor and Secondary Codes without

first presenting the configuration card.

When the Reader is powered up, it waits 4 seconds for a

configuration card to be presented. If it doesn’t read a configuration

card in this time, it enters the configured operating mode.

*All the features which can be set using the configuration card are

listed on the first page of chapter 3. It is most important that you

read and understand chapter 3 of this handbook before you

attempt to install a Reader.

Installing and connecting

PR500 Proximity Reader

The Reader is supplied with the cover separate. If the cover has been

fitted for any reason, remove it by pushing in the lug on its lower

edge using a suitable screwdriver.

1. Choose a suitable position to mount the Reader near the door.

The Reader has a maximum range of 30cm (12in) so it must be

mounted in a position where the card or tag can easily be

brought within this distance. We recommend it is mounted

approximately one metre (3.5ft) above the ground. Also

consider ease of access to the door once the card or tag has

been read, for example, it is better to mount the Reader near

the opening side of the door rather than the hinge side.

2. The Reader should be mounted with the LEDs at the top left.

Mark out and drill the two mounting holes. Don’t fix the

Reader to the wall yet. The holes accept 4mm machine screws

or No 8 wood screws.

3. Route the cables into the Reader: you can use either the cut-

out in the base or the one in the lower edge at the bottom of

the Reader.

The connections required for the Reader are power supply

connections (0V and +12V DC or +24V DC), data output

connections for Wiegand or Magnetic Stripe (D0, D1, DA) or

ASCII/TTL (H , D0, DA), and a connection from the host to the

Data Hold input (H ) if data lines from two Readers are to be

connected in parallel.

To promote EMC compliance we recommend you use 812

Cable as described here. Trim back and insulate the screens at

the PR500. Connect the screens at the host only: do not

connect the screens to the PR500.

4. When you have routed the cables into the Reader you can

screw it to the wall.

5. Make the connections shown in the following table:

*The PR500 is designed to be operated by 12V unregulated power supplies, or 24V

battery-backed power supplies. Operating voltage range is 10.6 to 32.0V. The upper

voltage is intended to be compatible with the charging of 24V lead-acid batteries.

Charge methods vary, and may be temperature dependent. 32V max is intended to

be compatible with commonly used charging methods. If the upper operating

voltage is exceeded then permanent damage may be caused. Installers and systems

designers should check the max power supply voltage under all conditions. Do not

operate the PR500 using unregulated 24V supplies. The PR500 current consumption

can be significantly less than 100mA. The unloaded peak voltage from a nominal

24V unregulated supply will exceed the absolute max.

6. Do not fit the front cover to the Reader until you have

configured it and tested it (see the end of this chapter).

HD500-2 Heavy Duty Proximity Reader

1. Choose a suitable position to mount the Reader near the door.

The Reader has a maximum range of 25cm (10in) so it must be

mounted in a position where the card or tag can easily be

brought within this distance. We recommend it is mounted

approximately one metre (3.5ft) above the ground. Also

consider ease of access to the door once the card or tag has

been read, for example, it is better to mount the Reader near

the opening side of the door rather than the hinge side.

2. You can mount the Reader using any of the six mounting holes

in the black plastic enclosure - the diagram at the end of this

section shows the fixing dimensions and is drawn actual size

so you can use it as a template when drilling the holes.

The Reader should be mounted with the strip of LEDs at the

top left.

Note that you do not need the stainless steel frame when

mounting the Reader - you fasten it to the Reader afterwards

to prevent anyone undoing the mounting screws.

3. Mark out and drill the mounting holes, but don’t fix the

Reader to the wall yet.

The holes accept 4mm machine screws or No 8 wood screws.

4. The connections required for the Reader are power supply

connections (0V and +12V DC or +24V DC), data output

connections for Wiegand or Magnetic Stripe (D0, D1, DA) or

ASCII/TTL (H, D0, DA), and a connection from the host to the

Data Hold input (H) if data lines from two Readers are to be

connected in parallel.

To promote EMC compliance we recommend you use 812

Cable as described here. Trim back and insulate the screens at

the HD500-2. Connect the screens at the host only: do not

connect any of the screens to the HD500-2.

*The HD500-2 is designed to be operated by 12V unregulated power supplies, or

24V battery-backed power supplies. Operating voltage range is 10.6 to 32.0V. The

upper voltage is intended to be compatible with the charging of 24V lead-acid

batteries. Charge methods vary, and may be temperature dependent. 32V max is

intended to be compatible with commonly used charging methods. If the upper

operating voltage is exceeded then permanent damage may be caused. Installers

and systems designers should check the max power supply voltage under all

conditions. Do not operate the HD500-2 using unregulated 24V supplies. The

HD500-2 current consumption can be significantly less than 100mA. The unloaded

peak voltage from a nominal 24V unregulated supply will exceed the absolute max.

#Two terminals are provided for use with a system 24hour tamper protection circuit.

These terminals are hard wired together on the Reader’s circuit board. If you connect

cables to these terminals, an open circuit will indicate that the wires have been cut.

5. Route the cable neatly then fix the Reader to the wall or door

frame.

6. Do not fit the stainless steel frame to the Reader until you

have configured it and tested it (see the end of this chapter).

7. When you have configured the Reader and tested it to make

sure that it is working correctly, you can fasten the Reader’s

stainless steel frame using the four “Resistorx” M4x12 screws

provided. These tamper-resistant screws can only be inserted

or removed using the correct tool which is not supplied with

1. The SP500 Reader fits a standard single surface-mount or

flush fitting back box, either metal or plastic, such as is used

for light switches and mains plug sockets.

The Reader has a maximum range of 30cm (12in) so it must be

mounted in a position where the card or tag can easily be

brought within this distance.

2. The connections required for the Reader are power supply

connections (0V and +12V DC or +24V DC), data output

connections for Wiegand or Magnetic Stripe (D0, D1, DA) or

Data Hold input (H) if data lines from two Readers are to be

connected in parallel.

To promote EMC compliance we recommend you use 812

Cable as described here. If the Reader is mounted in a plastic

back box then connect the screens at the host end only; at the

SP500 the screens must be cut back and insulated. If the

Reader is mounted in a metal back box then the overall screen

must be connected at the host end and also to the metal back

box. Do not connect any of the screens to the SP500 itself in

either of these situations.

Route the cables into the back box, then make the connections

shown in the table below.

PM500 Panel Mount Proximity Reader

1. The PM500 Reader can be mounted within a sheet metal or

plastic panel using four screws. If the panel is made of metal,

the Reader must be mounted behind a 40mm square cut-out

in the panel which must be positioned in the centre of the four

mounting holes as shown in the diagram overleaf.

When mounted in a metal panel, the Reader has a maximum

range of 15cm (6in) so it must be mounted in a position where

the card or tag can easily be brought within this distance.

2. The connections required for the Reader are power supply

connections (0V and +12V DC or +24V DC), data output

connections for Wiegand or Magnetic Stripe (D0, D1, DA) or

ASCII/TTL (H, D0, DA), and a connection from the host to the

Data Hold input (H) if data lines from two Readers are to be

connected in parallel.

To promote EMC compliance we recommend you use 812

Cable as described here. If the Reader is mounted in a plastic

panel then connect the screens at the host end only; at the

PM500 the screens must be cut back and insulated. If the

Reader is mounted in a metal panel then the overall screen

must be connected at the host end and also to the metal panel.

Do not connect any of the screens to the PM500 itself in either

of these situations.

Route the cables into the panel, then make the connections

shown in the table below.

Configuring and testing the Reader

1. If the Reader has already been configured by your supplier,

you can power it up and test it, see step 3 below.

2. If you need to configure the Reader yourself, power it up and

present the configuration card to the Reader within 4 seconds

of power up. During this 4 second period, the green LED is lit.

The Reader bleeps when it has read the configuration card and

the amber LED lights for a short period. After reading the

configuration card, the Reader gives you a further 8 seconds to

present one of the normal programmed cards which will be

used with the system. Doing this teaches the Reader its

Distributor and Secondary Codes. (If you do not present a

DC/SC card to the Reader within the 8 seconds, the Reader

enters its normal operating mode.)

The Reader bleeps when it has read the DC/SC card and the

amber LED lights for a short period. After the newly configured

hold-off time has elapsed, the Reader enters its normal

operating mode.

3. After configuring the Reader, test it by presenting a valid card.

The Reader’s LEDs should change from red to green (if the

LEDs are under internal control), the horn should bleep, and

the host should receive the data output.

4. If the Reader is working, you can complete the installation:

Clip the front cover in place on the PR500 and SP500 Readers.

Fit the stainless steel frame on the HD500-2 Reader using the

four “Resistorx” M4x12 screws provided. These tamper-

resistant screws can only be inserted or removed using the

correct tool which is not supplied with the Reader: it can be

obtained from Bewator Ltd as part number TX-20H.

Chapter 3

Setting up

You must set the following functions on a Reader before it will

operate correctly:

• Distributor Code

• Secondary Code

You will probably need to set the following:

• Data interface option

You may need to set the following:

• Horn operation

• Internal/external/single-wire control of LEDs

• Hold-off time and repeat data delay

• Leading parity calculation for Wiegand data output

• Position of Secondary Code in data output

• Secondary Code check disable

• ASCII interface protocol and baud rate

• Data Hold input signal polarity

Configuring the Reader

You configure the Reader by presenting it with two coded cards. The

first card (the configuration card) defines the type of data interface,

and all the features listed in the third group above. The second card

(any of the ordinary Distributor Coded cards which will be used with

the system) teaches the Reader its Distributor and Secondary Codes.

Note that you cannot teach the Reader its Distributor and Secondary

Codes without first presenting the configuration card.

When the Reader is powered up, it waits 4 seconds for a

configuration card to be presented. If it doesn’t read a configuration

card in this time, it enters its configured operating mode.

The configuration card

If you need to change the data interface or any of the other settings,

you need to use a configuration card programmed in 63 bit display

format on the 633-2 Programmer. Data fields in the configuration

card set up various options described below.

Proximity Readers Handbook

3-2

The configuration code is a 64-bit binary number which determines

how the Reader operates. Here is the complete 64-bit configuration

code, with each bit represented by a letter or number. The fields in

the code represented by the letters and numbers are defined in the

next section “Programming the configuration card”.

0xxs xxxx xxxx xxxx xxxx xbff xxxx xxxh xxhe hhhh pxxx xxrg crrr rrrr iiii iiii

The code is written down as sixteen 4-bit groups. Each 4-bit group

can be represented by a single hexadecimal digit which can be typed

directly into the 633-2 Programmer in 63-bit display format.

An x means that this bit of the code is not used.

(BCLINK users please note that “type” bits are not shown here.)

The next section “Programming the configuration card” defines each

of the fields in the configuration code. You should type each field into

the 633-2 Programmer in the order in which they are described. We

have shown a diagram with each entry, showing the position of the

hex character in the configuration code. For example, the hex

character determining the horn configuration is the ninth character:

00 000

Because the second to the fifth and the seventh characters are

unused, they are set to zero, and we have shown this in the diagram.

(Existing users please note that the new PR500 and HD500-2 may

require a slightly different configuration from the old PR500, HD500

and 5291 Readers.)

The DC/SC card

To teach the Reader its Distributor and Secondary Codes you use any

of the normal cards which will be used with the system (any of the

cards which are issued to cardholders). We shall call this the “DC/SC

card”.

Programming the configuration card

0xxs (secondary code swap)

00 000

The s bit determines whether the secondary code is output from the

Reader’s data interface as bits 33 to 48 (the position which it

occupies in the code which is programmed into the cards and tags),

or whether its position in the data output is swapped to bits 17 to 32.

Setting up

3-3

This feature is available so that cards programmed in the DEC/DEC

display format on the 633-2 Programmer can output secondary code

data using the 32-bit Wiegand or 26-bit Wiegand data interfaces

(interface numbers 02 and 12 hex respectively). This feature is invalid

for interfaces 47, 4D, 4E, 4F, 59, BC, BD and BE.

Secondary code swap bit (s):

0 the secondary code is output in its normal position (bits 33 to

48).

1 the secondary code is output in the swapped position (bits 17

to 32).

xbff (ASCII interface protocol and

00 000

baud rate)

The 3 bits bff determine the protocol and baud rate of the ASCII/TTL

interface. To work out the hex number you need to type into the

Programmer, refer to the following table:

Hex number ASCII protocol and baud rate

0 7 data bits, even parity, 1 stop bit, 1200 baud

1 7 data bits, odd parity, 1 stop bit, 1200 baud

2 7 data bits, no parity, 1 stop bit, 1200 baud

3 8 data bits, no parity, 1 stop bit, 1200 baud

4 7 data bits, even parity, 1 stop bit, 9600 baud

5 7 data bits, odd parity, 1 stop bit, 9600 baud

6 7 data bits, no parity, 1 stop bit, 9600 baud

7 8 data bits, no parity, 1 stop bit, 9600 baud

xxxh (Data Hold input signal polarity)

00 000

The h bit determines the polarity (active-low or active-high) of the

Data Hold input.

Note: if you are using the ASCII data output you must set Data Hold

to be active-high - the h bit must be set to 1.

To work out the hex number you need to type into the Programmer,

refer to the following table:

Hex number Data Hold polarity

xxhe (horn configuration)

00 000

The h bit determines whether the horn bleeps for 100ms when the

Reader reads a valid card.

The e bit determines how the horn operates when it is controlled

externally by the host. If this bit is 0, the horn sounds when the host

pulls the horn input down to 0V and continues sounding until the

host lets the horn input float high again. If this bit is 1, the horn

sounds for 1 second when the host pulls the horn input down to 0V

and then switches off automatically, irrespective of the state of the

horn input. (Note that while the horn is operating there may be some

loss of range, and the amber LED may flash.)

Hex number Internal control External control

0 100ms bleep follows horn input

1 100ms bleep sounds for 1 second

2 no bleep follows horn input

3 no bleep sounds for 1 second

hhhh (hold-off time)

00 000

When the Reader reads a valid card, it does not poll again until the

hold-off time has elapsed. During the hold-off time the Reader

maintains the state of the LED indicator (if the LEDs are under

internal control).

To work out the hex number you need to type into the Programmer,

refer to the following table:

pxxx (calculation of leading parity bit

00 000

for 26-bit Wiegand interfaces)

Leading parity bit (p):

0 the Reader does not calculate a leading parity bit.

8 the Reader calculates an even leading parity bit based on the

first 13 bits of the 26-bit Wiegand interface (interface number

12). This saves you from having to program the leading parity

bit into the cards. The trailing odd parity bit is still calculated

as normal.

xxrg (internal/external control of

00 00

red and green LEDs)

To work out the hex number you need to type into the Programmer,

refer to the following table:

Hex number Red LED Green LED

0 External External

1 Internal Internal

2 Internal External

Use the 0 setting when the drives for the red and green LED

indications are supplied by the host system. When you drive the

LEDs externally, you have to pull down the corresponding connection

from +5V to 0V. The R/G connection lights the green LED and the R

connection lights the red LED.

Use the 1 setting if you want the Reader alone to control the LEDs.

The red LED is lit when no card or tag is in range. The green LED

lights after a valid card read and stays on until the card is removed

from the reading area of the Reader, or the hold off time expires,

whichever is longer. The amber LED flashes if there is electrical noise

in the reading area which may affect reading of cards and tags.

The 2 setting requires external control of the green LED from the

host, but the Reader controls red and amber LEDs. This provides

single-wire control of the LED indication from the host. It works as

follows:

• The red LED is lit when no card or tag is in range.

• When the Reader reads a card or tag, the host processes the

data from the Reader, unlocks the door and lights the green

LED by pulling the R/G connection down to 0V. This also

turns the red LED off.

• When the host releases the green LED control, the green LED

goes off and the red LED lights.

Proximity Readers Handbook

• The amber LED flashes if there is electrical noise in the

reading area which may affect reading of cards and tags.

crrrrrrr (Secondary Code check

00 000

13 14

disable, and repeat data delay - RDD)

Bit c, when set to 1, disables the Secondary Code check so the

Reader outputs data from a card or tag without checking that the

Secondary Code is valid. (This bit does not affect interfaces 47, 59,

BC, BD or BE.)

The seven bits rrrrrrr set the repeat data delay time or RDD. If you

set these bits to any number from 0 to 127 (00 to 7F in hex), the RDD

is set to this number of seconds (note that the timings are

approximate). You must convert the decimal number into

hexadecimal, for example, 10 is AH, 20 is 14H, etc. If you are setting

bit c, remember that you will have to add 128 (80 in hex) to the RDD

value.

What is the Repeat Data Delay? When the Reader reads data from a

card, it sends card data to the host. After it has done this, it will not

send the same card data to the host again until the RDD time has

elapsed. This prevents the system becoming overloaded with lots of

data from one card being read over and over again.

iiiiiiii (interface number)

00 000

1615

This field sets the data interface number (two hexadecimal digits). See

the chapter on data interfaces and, if necessary, contact your

supplier to find out what setting you should be using. The interface

number given to you by your supplier is a two digit hexadecimal

number and therefore can be entered directly into the 633-2

Programmer without conversion.

Note: the Proximity Readers have a limited set of interfaces available

compared with earlier Readers. Please check that the interface

number you are using is available on the Reader - the following

interface numbers are available: 02, 04, 0E, 12, 24, 47, 4D, 4E, 4F,

59, 60, 64, BC, BD and BE.

Note to existing users of PR500 and HD500

We have changed the configuration slightly in the new Readers. For

many interface settings, the repeat data delay and secondary code

check disable were built into the chosen interface number. You now

have the option of changing these, but if you wish to keep the same

operating style you will have to modify your configuration card.

Please refer to the description of the available interfaces in chapter 4.

Programming the DC/SC card

The card you use to teach the Reader the Distributor and Secondary

Codes can be any normal Distributor Coded card programmed with

the correct Secondary Code (any of the cards which are issued to

cardholders).

Set your 633-2 Programmer to any of the Distributor Coded display

formats (usually Dec/Dec, but could be Hex/Dec or Hex/Hex or

Hex/BCD), enter the correct Secondary Code in the SITE or

SECONDARY field and program the card (the card number does not

matter).

Presenting configuration card and DC/SC

card to the Reader

1. Power up the Reader and present the configuration card within

4 seconds of power up. During this 4 second period, the green

LED is lit.

The Reader bleeps when it has read the configuration card and

the amber LED lights for a short period.

2. After reading the configuration card, the Reader gives you a

further 8 seconds to present one of the normal programmed

cards which will be used with the system. Doing this teaches

the Reader its Distributor and Secondary Codes. (If you do not

present a DC/SC card to the Reader within the 8 seconds, the

Reader enters its normal operating mode.)

The Reader bleeps when it has read the DC/SC card and the

amber LED lights for a short period. After the newly configured

hold-off time has elapsed, the Reader enters its normal

operating mode.

Changing the Secondary Code or Distributor

Code

If, after setting the Distributor and Secondary Code, you need to

change either of them, power up the Reader, present the

configuration card within 4 seconds and then present the new DC/SC

card within 8 seconds.

Examples of working out what to program

into the configuration card in 63-bit mode on

the Programmer

When you refer to the earlier section entitled “Programming the

configuration card”, you can look up the hexadecimal numbers you

need in the tables and write them down as you go. You then enter the

hexadecimal numbers into the Programmer in 63-bit display format.

If you ever need to convert decimal and binary numbers to

hexadecimal digits, here is a table giving the decimal (top row), binary

(middle row) and hexadecimal (bottom row) equivalents for all

possible 4-bit numbers:

0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Data interfaces

The Reader Interface offers a choice of Wiegand or Magnetic Stripe

data output to communicate with a host system. An ASCII data

output is also available at TTL voltage levels (0V/+5V), which can be

converted to an RS232 data output using the optional 5810 RS232

Converter. You select the interface you require by programming a 63-

bit configuration card and presenting it to the Reader, see chapter 3.

(The Readers are available in AB format if you require BCLINK data

output, but this option is not described in this handbook.)

Electrical characteristics of outputs from the

Reader

The Wiegand and Magnetic Stripe interfaces use the data lines D0,

D1 and DA. The ASCII/TTL interface uses D0 and DA, and input H.

The D1 and DA outputs are driven by open drain drivers which can

each sink up to 250mA. When a driver is off, its output is pulled up

to +5V (the regulated logic voltage on the board) by a 10k resistor

(and also by whatever is connected at the host end). D0 is not pulled

up - it can be driven high or low by the Reader, and can also float in

a high impedance state as shown in the diagram below.

The diagram below shows the logical implementation of the data

outputs:

+5V

10k 10k

47R

Proximity Readers Handbook

4-2

The polarities of the three data outputs (D0, D1 and DA) are all

active-low.

Data Hold input

With the Wiegand and Magnetic Stripe interfaces, the Data Hold

input (H) can be used by the host to buffer one data message in the

Reader until the host is ready to read it. This enables the data lines

from two Readers to be connected in parallel, the host polling each in

turn by releasing its Data Hold input, reading the data, then

asserting the Data Hold input again. The Reader will store the

message until the next card is read.

With the ASCII/TTL interface, the Data Hold input (H) is used as the

CTS input to the Reader.

Wiegand

Connections

The pin connections for the Wiegand interface are as follows:

0V (ground)

D0 (logic 0)

D1 (logic 1)

DA (data available)

Electrical characteristics

The interface provides three outputs: logic zero data (D0), logic one

data (D1) and data available (DA).

Data transfer is performed by pulsing the D0 line to indicate a logic

zero and by pulsing the D1 line to indicate a logic one. The pulses are

active-low. The voltage of the data lines is +5V or 0V.

The Data Available output (DA) is provided to tell the host system it

must read a data message from the Reader. If the Data Hold input

(see above) is not active, DA becomes active 1ms before data is sent

and is released 1ms after the data has been sent. If the Data Hold

input is active, DA becomes active but data is not sent until Data

Hold is released, DA remaining active until 1ms after the data has

been sent. When used in association with the Data Hold input (see

above), DA enables the data lines from two Readers to be connected

in parallel. The polarity of the DA output is active-low.

Data interfaces

4-3

Data format

There are three aspects to the format of the data message, all of

which can be varied, depending on the interface number you use:

• Framing bits at the start and finish of the message.

• Any parity bits which may be used.

• The data from the card.

The following diagram shows a typical message structure.

LSB

Data Framing

Transmitted last

Framing

Transmitted first

Trailing

Parity

Leading

Parity

MSB

Framing bits are usually either not used or confined to start and stop

bits which have a fixed state.

Parity bits are used to check the integrity of the data message. Parity

may be odd or even and it may be calculated from the data only or

from the data and some framing bits. The Reader can calculate the

leading parity bit based on the first 13 bits of 26-bit Wiegand format

if you require, see chapter 3.

Card data

Data from the card can be any number of bits up to a maximum of

48. This includes any parity check bits which may be stored in the

card code. The interface selected also determines whether the data is

sent most significant bit first or least significant bit first.

Proximity Readers Handbook

4-4

Interface settings

All other options to do with the Wiegand interface such as variation of

pulse width and interval are selected using the interface number

programmed into the configuration card (see chapter 3). The following

diagram shows some typical timings for a Wiegand interface:

Note: if you cannot use one of the above data output formats then

you need to use a different Reader such as the 5311 driving a PR100,

HD100, SP100 or PM100 Reading Head.

Data interfaces

4-5

Magnetic Stripe

A Magnetic Stripe interface is provided which simulates the output of

a magnetic card reader.

Connections

The pin connections for the Magnetic Stripe interface are as follows:

0V (ground)

D0 (data)

D1 (strobe)

DA (present)

Electrical characteristics

The interface provides three outputs: Present, Data and Strobe.

Present is a signal given by a magnetic card reader indicating that a

card has been inserted in the slot. On the Proximity Readers, this

signal becomes active just before data is sent and is released after the

data has been sent. The polarity of the signal is active-low.

Data is a signal whose level reflects the value of the bit in the code.

The polarity of the signal is “inverse logic”, which means a high signal

indicates a zero and a low signal indicates a one.

Strobe is a series of clock pulses. The polarity of the signal is active-

low. Data can be sampled on either the rising edge or the falling edge

of the Strobe signal.

The following diagram should make clear the action of all three

signals in a data transfer:

Present (DA)

Strobe (D1)
